Question

Define power Give its SI unit prove that
P=EV. where F = force
V = Velocity​

Answer 1

Answer:

power is the rate of doing the work.

mathematically, Power(P) = Workdone/ time

or P = dw/dt

Si unit Of power is Watt or J/s.

Explanation:

P= dw/dt

or P= F. ds/dt

therefore P= F.v since ds/dt = v

Answer 2

Answer:

In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. ... The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft.

SI unit: watt (W)

In SI base units: kg⋅m2⋅s−3
